Dear Jeff
Thank you for your guiding. I have simulated my HVAC system at nominal condition, alone not using the building model. Now I'm going to use this system connected to a building. Now my question is how should I match the HVAC cooling production to the building load which is transient? should I control the temperature and humidity also or just the flow rate should be controlled to meet the load?
I couldn't find a similar example in TRNSYS examples. Could you send me an example in case of having some please?
Thank you
Ahmad,
There are literally hundreds of ways to control the temperature and humidity in a space. I would suggest you do some reading to figure out a common HVAC system given your climate and type of building - then you can begin to replicate that system in TRNSYS.
Jeff

Hello
I'm simulating a solar assisted coolig system for a building. The building cooling load is transient. so how the HVAC system should be controlled to cover the building load? I guess that the supply air temperature and humidity ratio should be constant ( a value in the comfort region ) and the air flow rate should be controlled using a variable speed fan to cover the cooling load. Is it right? any better idea?
Also I don't know how the control system should be? should I use a thermostat?
If any one can send me an example it will be very useful for me to learn
Thank you
